BACKGROUND AND AIM Hepatitis B virus (HBV) surface antigen (HBsAg) seroreversion usually occurs during immunosuppressive therapy. The risk and factors of HBsAg seroreversion from resolved HBV infection in the general population remained unclear. METHODS This retrospective study enrolled subjects with resolved HBV infection and who had received at least two times of screening in a longitudinal community screening program. HBsAg, hepatitis B surface antibody (anti-HBs), and hepatitis C virus antibody (anti-HCV) were tested every time in all subjects. The primary endpoint was HBsAg seroreversion. RESULTS Of the 7630 subjects enrolled, 5158 (67.6%) subjects had positive anti-HBs at baseline. HBsAg seroreversion occurred in 84 subjects during 42 815-person-year follow-up with an annual incidence of 0.2% and a 10-year cumulative risk of 1.9%. Anti-HBV treatment-experienced subjects had a significantly higher risk of HBsAg seroreversion than anti-HBV treatment-naive subjects (83/310 [26.8%] vs 1/7320 [0.01%], P

Hepatitis C virus eradication via the use of antivirals ameliorates metabolic profiles. The changes in serum uric acid (SUA) levels in chronic hepatitis C patients who receive antivirals are not well understood. We aimed to address this issue by comparing the SUA changes before and after the achievement of a sustained virological response (which is defined as hepatitis C virus RNA seronegativity at 12 weeks after the end of treatment).Two hundred and thirteen sustained virological response patients who were treated by directly acting antivirals were consecutively enrolled. Pretreatment and post-treatment SUA levels were compared. Hyperuricemia was defined as a uric acid level 7.0 mg/dL in men and 6.0 mg/dL in women.The SUA levels significantly decreased after treatment, as compared to the pretreatment levels (5.6 ± 1.5 vs 6.0 ± 1.7 mg/dL, respectively; P 0.001). The proportion of hyperuricemia incidences significantly decreased after treatment (25.8% vs 35.7%, respectively; P = 0.001). The improvement was only observed in patients with a fibrosis-4 index (FIB-4) 6.5 (25.7% vs 37.1%, P = 0.001) but not in those patients with a FIB-4 ≧ 6.5 (26.3% vs 28.9%, P = 1.00). A multivariate analysis revealed that the factor that was associated with significantly decreased SUA levels was FIB-4 6.5 (odds ratio [OR]/95% confidence interval [CI]: 3.22/1.04-9.95, P = 0.04) and estimated glomerular filtration rate 60 mL/min/1.73 mSUA levels were significantly decreased in chronic hepatitis C patients after viral eradication. The improvement was particularly enhanced in patients with mild liver disease.

Background and aim The prevalence of mixed cryoglobulinemia is 15-50% in chronic hepatitis C (CHC) patients, and these patients are in an increased risk of liver fibrosis and cirrhosis, but it is controversial. This study aimed to reveal the prevalence of mixed cryoglobulinemia in Asian population and to determine the relationship between presence of serum cryoglobulinemia and liver fibrosis in CHC patients with or without liver biopsy. Methods In total, 2255 treatment-naive patients retrospectively enrolled in our study. Serum cryoglobulinemia precipitation, liver biopsy, and four indexes of fibrosis (FIB4) were assessed to detect the associated factors. Results Three hundred sixty-four (32%) out of 1135 liver biopsy patients and 341 (30.4%) out of 1120 non-biopsy patients were positive for serum cryoglobulinemia. Multivariate analysis revealed that male gender, hepatitis C virus RNA, platelet and advanced fibrosis (odds ratio [OR] 1.40, 95% confidence interval [CI] 1.05-1.87, P = 0.021) were significantly associated with the presence of cryoglobulinemia in the liver biopsy proven patients. The presence of serum cryoglobulinemia (OR 1.43, 95% CI 1.04-1.96, P = 0.026) was associated with advanced liver fibrosis (F3 and F4) by multivariate logistic regression analysis. In patients without liver biopsy, FIB4 (OR 1.72, 95% CI 1.30-2.27, P = 0.0001) was associated with the presence of serum cryoglobulinemia, and also cryoglobulinemia (OR 1.74, 95% CI 1.32-2.30, P = 0.0001) was associated with high FIB4 (≥ 3.25) patients. Conclusion The prevalence of the presence of serum cryoglobulinemia is 30.4-32% in CHC patients and associated with advanced fibrosis in liver biopsy proven patients and high-FIB4 (≥ 3.25) patients without liver biopsy.

Background and Aim Hepatitis B virus (HBV) may reactivate when treating chronic hepatitis C (CHC) with direct acting antivirals (DAA). We aim to investigate the risk of HBV reactivation during DAA therapy. Methods Chronic hepatitis C patients receiving pan-oral DAA therapy from December 2013 to August 2016 were evaluated. Fifty-seven patients that had a past HBV infection (negative hepatitis B surface antigen [HBsAg] and positive hepatitis B core antibody) and seven patients that had a current HBV infection (positive HBsAg) were enrolled. Serum HBV and hepatitis C virus (HCV) markers were regularly measured. The endpoints were the HCV sustained virological response (SVR) and the HBV virological/clinical reactivation. Results The overall SVR12 rate was 96.9%, and two patients, one with positive HBsAg, had a relapse of HCV. No episodes of HBV virological reactivation were observed among the patients with a past HBV infection. For the seven patients with a current HBV infection, HBV virological reactivation was found in four (57.1%) of the seven patients. Clinical reactivation of HBV was observed in one patient with pretreatment detectable HBV DNA and recovered after entecavir administration. For the other three patients with HBV virological reactivation, the reappearance of low level HBV DNA without clinical reactivation was observed. HBsAg levels demonstrated only small fluctuations in all the patients. Conclusions There was a minimal impact of hepatitis B core antibody seropositivity on HCV efficacy and safety. For CHC patients with current HBV infection, the risk of HBV reactivation was present, and monitoring the HBV DNA level during therapy is warranted.

BACKGROUND/AIMS The erythropoiesis in hepatitis C virus infection is unclear. We aimed to evaluate the erythropoietic components in chronic hepatitis C (CHC) patients. METHODS The red blood cell (RBC) components, serum erythropoietin (EPO) levels, and their relationship to clinical characteristics were evaluated between 124 age-matched and sex-matched healthy controls and 248 histology-proven CHC patients. RESULTS Chronic hepatitis C patients had significantly higher serum levels of EPO (1.44 ± 0.36 log mIU/mL versus 1.03 ± 0.31 log mIU/mL, P

BACKGROUND The optimal therapeutic strategy for hepatitis B virus (HBV) e antigen (HBeAg)-seropositive and hepatitis C virus (HCV) dually infected patients remains unknown. We aimed to elucidate the effectiveness of peginterferon (Peg-IFN)/ribavirin (RBV) with and without lamivudine (LAM) combination therapy in the clinical settings. PATIENTS AND METHODS Nine patients seropositive for HBV surface antigen, HBeAg, antibodies to HCV and HCV RNA for >6 months were treated with Peg-IFN/RBV with (n = 5) and without (n = 4) a 12-month LAM add-on therapy at treatment week 12. The treatment duration of Peg-IFN/RBV was 24 weeks (HCV genotype 1 [HCV-1] with rapid virological response [RVR] or HCV-2) or 48 weeks (HCV-1 without RVR). Primary endpoints included HBeAg loss and HCV-sustained virological response (SVR). RESULTS All of the nine patients had undetectable HCV RNA at treatment weeks 4 and 12 and end-of-Peg-IFN/RBV therapy. However, SVR was achieved in 100% of patients treated with triple therapy, compared with only 50% in those with Peg-IFN/RBV therapy (P = 0.167). The 3-year durability of HCV SVR was 100%. HBeAg loss and HBV DNA

Background and Aim Chronic hepatitis C virus (HCV) infection has been suggested to be associated with non-insulin-dependent diabetes mellitus and lipid profiles. This study aimed to investigate the possible relationships of insulin resistance (IR) and lipid profiles with chronic hepatitis C (CHC) patients in Taiwan. Methods We enrolled 160 hospital-based CHC patients with liver biopsy and the 480 controlled individuals without CHC and chronic hepatitis B from communities without known history of non-insulin-dependent diabetes mellitus. Fasting plasma glucose, total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), alanine aminotransferase, and serum insulin levels, and homeostasis model assessment (HOMA-IR) were tested. Results When comparing factors between CHC patients, and sex- and age-matched controls who had no HCV infection, patients with HCV infection had a significantly higher alanine aminotransferase level, fasting plasma glucose level, insulin level, and HOMA-IR (P 2.5]), a high body mass index, TGs, and HCV RNA level are independent factors significantly associated with high HOMA-IR in multivariate logistic analyses. Conclusions Chronic HCV infection was associated with metabolic characteristics including IR and lipid profile. IR was also associated with virological characteristics.

Background and Aim The treatment efficacy of patients with mixed hepatitis C virus (HCV) genotype 1/genotype 2 (HCV-1/2) remains unknown. We aimed to elucidate the sustained virological response (SVR) rate in patients with HCV-1/2 infection. Methods One hundred and ten HCV-1/2 patients treated with response-guided peginterferon/ribavirin therapy (24 weeks for patients with a rapid virological response [RVR] and low viral loads; 48 weeks for patients without a RVR or high viral loads) were allocated. Two hundred HCV-1 patients were selected as a historical control. Interleukin-28B (IL-28B) rs8099917 genotype was tested for the association with an SVR. Results The rates of RVR, sustained virologic response (SVR), and relapse rate were 71.8%, 87.3%, and 11.1%, respectively. The SVR rate was significantly higher in patients with an abbreviated regimen as compared with those with 48-week regimen (95.5% vs 75.0%, P = 0.002), and both were similar to the HCV-1 historical control. Stepwise logistic regression analysis revealed that lower baseline viral loads were the single factor predictive of an RVR (odds ratio/95% confidence intervals [OR/CI] of 41.62/9.72–178.19, P

Background and Aim Host interleukin-28B (IL-28B) genetic variants determine a sustained virological response (SVR) in hepatitis C virus genotype 1 (HCV-1) treatment-naive patients. Its impact on treatment-experienced Asian patients with peginterferon/ribavirin in is to be elucidated. Methods IL-28B rs8099917 genotype was determined in 70 HCV-1 treatment-experienced patients retreated with 48-week peginterferon/ribavirin. Results The SVR rate was 60.0% and was significantly higher in previous relapsers than in nonresponders (72.7% and 13.3%, P

The erythropoiesis in hepatitis C virus infection is unclear. We aimed to evaluate the erythropoietic components in chronic hepatitis C (CHC) patients.The red blood cell (RBC) components, serum erythropoietin (EPO) levels, and their relationship to clinical characteristics were evaluated between 124 age-matched and sex-matched healthy controls and 248 histology-proven CHC patients.Chronic hepatitis C patients had significantly higher serum levels of EPO (1.44 ± 0.36 log mIU/mL versus 1.03 ± 0.31 log mIU/mL, P 0.0001) and lower hemoglobin (Hb) concentrations (14.6 ± 1.4 g/dL versus 15.3 ± 1.2 g/dL, P 0.001) as compared with healthy controls. Among the CHC patients, the serum EPO level was negatively associated with the Hb concentration (β = -0.227; 95% confidence intervals [CI]: -0.09-0.027; P 0.001) and RBC counts (β = -0.204; 95% CI: -0.245-0.061; P = 0.001) and was positively correlated with necroinflammatory activity (β = 0.201; 95% CI: 0.009-0.046; P = 0.003) and fibrosis (β = 0.143; 95% CI: 0.003-0.076; P = 0.04) of liver histopathology. For non-cirrhotic CHC patients, the severity of liver necroinflammatory activity was positively correlated with the reticulocyte and serum EPO levels (P = 0.001 and 0.008, respectively), and negatively related to the RBC counts (P = 0.03). Using stepwise multivariate linear regression analysis, the grade of necroinflammatory activity was positive (β = 0.214; 95% CI: 0.046-0.209, P = 0.002), whereas the Hb concentration was inversely (β = -0.205; 95% CI: -0.09-0.018, P = 0.004) associated with the serum EPO levels in CHC patients.The disease activity in CHC patients had a negative impact on erythropoiesis with compensatory higher but blunted EPO responses.

Background and Aim: Cytokines activation is a common feature in chronic hepatitis C (CHC) infection. Visfatin, as a recently-recognized adipocytokine, may correlate with metabolic abnormalities. We aimed to elucidate the characteristics of visfatin in CHC patients. Methods: This retrospective study included 102 treatment-naive CHC patients and 97 sex-/age-matched healthy adults. Serum visfatin levels were examined by an enzyme linked immunosorbent assay test. The correlation between visfatin and hepatitis C virus (HCV) infection in terms of virological, metabolic, and histopathological profiles was analyzed. The impact of visfatin on the treatment response to pegylated interferon plus ribavirin (PEGIFN/RBV) therapy was also assessed. Results: The visfatin level was correlated significantly with fibrosis scores (r = 0.23, P = 0.02) in CHC patients. A significant higher visfatin level was observed in CHC patients with histological activity index scores of mild and more (P = 0.01) and advanced fibrosis (P = 0.04). The mean visfatin level (0.81 ± 0.28 log ng/mL) of 26 CHC patients with metabolic syndrome was significantly lower than their counterparts (0.95 ± 0.30 log ng/mL) (P = 0.03). There was no significant correlation between visfatin and HCV genotypes, viral load, and treatment response to PEGIFN/RBV therapy. Multiple logistic regression analyses demonstrated that metabolic syndrome was the leading negative variable (odds ratio = 0.09, 95% confidence interval = 0.02–0.46, P = 0.004) associated with high visfatin level, followed by advanced fibrosis (odds ratio = 2.88, 95% confidence interval = 1.06–6.78, P = 0.03). Conclusions: Serum visfatin was correlated with disease severity and metabolic syndrome in CHC patients.

The optimal therapeutic strategy for hepatitis B virus (HBV) e antigen (HBeAg)-seropositive and hepatitis C virus (HCV) dually infected patients remains unknown. We aimed to elucidate the effectiveness of peginterferon (Peg-IFN)/ribavirin (RBV) with and without lamivudine (LAM) combination therapy in the clinical settings.Nine patients seropositive for HBV surface antigen, HBeAg, antibodies to HCV and HCV RNA for6 months were treated with Peg-IFN/RBV with (n = 5) and without (n = 4) a 12-month LAM add-on therapy at treatment week 12. The treatment duration of Peg-IFN/RBV was 24 weeks (HCV genotype 1 [HCV-1] with rapid virological response [RVR] or HCV-2) or 48 weeks (HCV-1 without RVR). Primary endpoints included HBeAg loss and HCV-sustained virological response (SVR).All of the nine patients had undetectable HCV RNA at treatment weeks 4 and 12 and end-of-Peg-IFN/RBV therapy. However, SVR was achieved in 100% of patients treated with triple therapy, compared with only 50% in those with Peg-IFN/RBV therapy (P = 0.167). The 3-year durability of HCV SVR was 100%. HBeAg loss and HBV DNA2000 IU/mL at 6 months post-LAM treatment were found in 100% and 40% of patients treated with triple therapy, compared with none of the four patients with Peg-IFN/RBV therapy achieved any HBV responses. Of the five patients with triple therapy, four had persistent HBeAg loss during 3-year follow-up period; one developed HBeAg seroreversion 15 months after treatment.For HBeAg-positive HBV/HCV dually infected patients, Peg-IFN/RBV was effective for HCV eradication. Add-on LAM might promote HBeAg loss in the clinical setting.

Background: The aim of the present study was to compare the histological characteristics of livers between chronic hepatitis C (CHC) patients with and without hepatitis B virus (HBV) coinfection. Methods: A total of 336 CHC patients (male/female: 204/132, mean age: 46.1 ± 11.7 years) were enrolled in the study; 32 patients (9.8%) were positive for hepatitis B surface antigen (HBsAg). The histological characteristics of livers were described according to the Knodell and Scheuer scoring system. Results: The proportion of non-intralobular necrosis (score 0) was significantly lower and the mean intralobular necrosis score was higher among CHC patients with HBV coinfec- tion than those without coinfection (43.8% vs 64.5%; 0.84 ± 1.05 vs 0.53 ± 0.89). The epidemiological and virological parameters, and other histological scores (periportal necrosis, portal inflammation, total necroinflammation and fibrosis) were not significantly different between these two groups. Conclusion: Chronic hepatitis C patients with HBV coinfection tend to have more severe intralobular necrosis than those with isolated HCV infection.

The treatment efficacy of patients with mixed hepatitis C virus (HCV) genotype 1/genotype 2 (HCV-1/2) remains unknown. We aimed to elucidate the sustained virological response (SVR) rate in patients with HCV-1/2 infection.One hundred and ten HCV-1/2 patients treated with response-guided peginterferon/ribavirin therapy (24 weeks for patients with a rapid virological response [RVR] and low viral loads; 48 weeks for patients without a RVR or high viral loads) were allocated. Two hundred HCV-1 patients were selected as a historical control. Interleukin-28B (IL-28B) rs8099917 genotype was tested for the association with an SVR.The rates of RVR, sustained virologic response (SVR), and relapse rate were 71.8%, 87.3%, and 11.1%, respectively. The SVR rate was significantly higher in patients with an abbreviated regimen as compared with those with 48-week regimen (95.5% vs 75.0%, P = 0.002), and both were similar to the HCV-1 historical control. Stepwise logistic regression analysis revealed that lower baseline viral loads were the single factor predictive of an RVR (odds ratio/95% confidence intervals [OR/CI] of 41.62/9.72-178.19, P 0.001). The achievement of an RVR was the single best factor predictive of an SVR (OR/CI: 7.5/1.33-42.27, P = 0.02). Nevertheless, an abbreviated regimen became the single factor associated with an SVR if treatment regimen was taken into consideration (OR/CI: 11.0/1.25-96.79, P = 0.03). The SVR rate did not differ between patients with rs8099917 TT and TG/GG genotype (91.7% vs 87.5%, P = 0.63).The treatment efficacy of patients with HCV-1/2 was satisfactory. The role of IL-28B genetic variants in the population with response-guided therapy was limited.

Chronic hepatitis C virus (HCV) infection has been suggested to be associated with non-insulin-dependent diabetes mellitus and lipid profiles. This study aimed to investigate the possible relationships of insulin resistance (IR) and lipid profiles with chronic hepatitis C (CHC) patients in Taiwan.We enrolled 160 hospital-based CHC patients with liver biopsy and the 480 controlled individuals without CHC and chronic hepatitis B from communities without known history of non-insulin-dependent diabetes mellitus. Fasting plasma glucose, total cholesterol, high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), triglycerides (TGs), alanine aminotransferase, and serum insulin levels, and homeostasis model assessment (HOMA-IR) were tested.When comparing factors between CHC patients, and sex- and age-matched controls who had no HCV infection, patients with HCV infection had a significantly higher alanine aminotransferase level, fasting plasma glucose level, insulin level, and HOMA-IR (P 0.001, P = 0.023, P = 0.017, and P = 0.011, respectively), and significantly lower TG level (P = 0.023), total cholesterol, and HDL-C and LDL-C levels (all P 0.001) than 480 controls. In multivariate logistic regression analyses, a low total cholesterol, a low TGs, and a high HOMA-IR are independent factors significantly associated with chronic HCV infection. In the 160 CHC patients (41 patients with high HOMA-IR [ 2.5]), a high body mass index, TGs, and HCV RNA level are independent factors significantly associated with high HOMA-IR in multivariate logistic analyses.Chronic HCV infection was associated with metabolic characteristics including IR and lipid profile. IR was also associated with virological characteristics.

Host interleukin-28B (IL-28B) genetic variants determine a sustained virological response (SVR) in hepatitis C virus genotype 1 (HCV-1) treatment-naïve patients. Its impact on treatment-experienced Asian patients with peginterferon/ribavirin in is to be elucidated.IL-28B rs8099917 genotype was determined in 70 HCV-1 treatment-experienced patients retreated with 48-week peginterferon/ribavirin.The SVR rate was 60.0% and was significantly higher in previous relapsers than in nonresponders (72.7% and 13.3%, P 0.001). Multivariate analysis revealed that the most important factor predictive of an SVR was previous relapse (Odds ratio [OR]/95% confidence interval [CI]: 14.76/2.72-80.06, P = 0.002), followed by the carriage of rs8099917 TT genotype (OR/95% C.I.: 7.67/1.27-46.49, P = 0.03). Comparing to patients with TG/GG genotype, those with TT genotype had significantly higher rates of rapid virological response (29.3% vs 0%, P = 0.03), end-of-treatment virological response (86.2% vs 50.0%, P = 0.01), SVR (69.0% vs 16.7%, P = 0.002), and lower relapse rate (22.0 % vs 66.7%, P = 0.04). The SVR rate was similarly low between previous nonresponders with different rs8099917 genotypes (12.5% vs 14.3%, P = 1). On the contrary, previous relapsers with rs8099917 TT genotype had a significantly higher SVR rate than those who carried rs8099917 TG/GG genotype (78.0 % vs 20.0%, P = 0.02). Stepwise logistic regression analysis revealed that the only factor predictive of an SVR in previous relapsers was the carriage of rs809997 TT genotype (OR/95% CI:18.50/1.82-188.39, P = 0.014).Host IL-28B genetic variants played a role in Asian relapsers but not nonresponders retreated with peginterferon/ribavirin. Direct antiviral agents might be possibly avoidable in Asian relapsers with favorable IL-28B genotype.

Cytokines activation is a common feature in chronic hepatitis C (CHC) infection. Visfatin, as a recently-recognized adipocytokine, may correlate with metabolic abnormalities. We aimed to elucidate the characteristics of visfatin in CHC patients.This retrospective study included 102 treatment-naïve CHC patients and 97 sex-/age-matched healthy adults. Serum visfatin levels were examined by an enzyme linked immunosorbent assay test. The correlation between visfatin and hepatitis C virus (HCV) infection in terms of virological, metabolic, and histopathological profiles was analyzed. The impact of visfatin on the treatment response to pegylated interferon plus ribavirin (PEGIFN/RBV) therapy was also assessed.The visfatin level was correlated significantly with fibrosis scores (r = 0.23, P = 0.02) in CHC patients. A significant higher visfatin level was observed in CHC patients with histological activity index scores of mild and more (P = 0.01) and advanced fibrosis (P = 0.04). The mean visfatin level (0.81 ± 0.28 log ng/mL) of 26 CHC patients with metabolic syndrome was significantly lower than their counterparts (0.95 ± 0.30 log ng/mL) (P = 0.03). There was no significant correlation between visfatin and HCV genotypes, viral load, and treatment response to PEGIFN/RBV therapy. Multiple logistic regression analyses demonstrated that metabolic syndrome was the leading negative variable (odds ratio = 0.09, 95% confidence interval = 0.02-0.46, P = 0.004) associated with high visfatin level, followed by advanced fibrosis (odds ratio = 2.88, 95% confidence interval = 1.06-6.78, P = 0.03).Serum visfatin was correlated with disease severity and metabolic syndrome in CHC patients.

Background and Aim: A number of hepatitis C virus (HCV) patients without a rapid virological response (RVR) achieved a sustained virological response (SVR) with peginterferon-α-2a/ribavirin. The aim of this study was to identify factors associated with SVR in non-RVR patients. Methods: Baseline and on-treatment factors were used to explore the prognostic factors for SVR in 113 HCV genotype-1 (HCV-1) and 20 HCV-2 non-RVR patients in two randomized trials. Results: The SVR rate in HCV-1 patients with a complete early virological response (cEVR) and partial early virological response was 91.9% versus 45% (P
